M. Davis in Science 19 Apr. 629/2 Streams of this kind might be called reversional consequents, renewed consequents, reconsequents, or simply resequents. 1970 R. J. Small Study of Landforms vii. 235 Synclinal streams may even be ‘resequents’, which are traditionally regarded as the eventual outcome of drainage development in areas of folded rocks. 1987 S. N. Pandey Princ. & Applic. Photogeol. x. 156 Streams in the first two cases will normally be subsequents while in the last case, they may be consequents, resequents, obsequents or obsequent-subsequents. B. adj. 1. Designating, or characterized by the presence of, a stream or streams whose course follows the dip of strata (in the manner of a consequent stream) but is at a lower level than the original surface of the underlying geological formation.

M. Davis in Science 17 Oct. 637/1 Thus an encircling (subsequent) valley is developed with a new series of radial streams (resequent) from the stripped mountain core. 1937 S. W. Wooldridge & R. S. Morgan Physical Basis Geogr. xv. 212 A good example is afforded by the Central Weald of Kent and Sussex, where there are many good examples of synclinal valleys for which resequent origin must be deemed probable. 1970 R. J. Small Study of Landforms iii. 91 Where inversion of relief has once been achieved, continued erosion can lead to a restoration of the original structure-relief relationship; the synclinal valleys and anticlinal ridges are then, strictly speaking, ‘resequent’. 1991 Mountain Res. & Devel. 11 282/1 A 10-km section of the Bagmati River was selected where it follows a resequent course. 2008 D. R. Oldroyd et al. in R. H. Grapes et al. Hist. Geomorphol. & Quaternary Geol. 249/2 Twidale and Campbell..have rightly remarked that the old terminology of consequent, subsequent, obsequent, and insequent streams is most unsatisfactory. They recommend the use of the terms dip, strike, anti-dip, fault, anticlinal, synclinal or monoclinal as appropriate. 2. Of a fault-line scarp or a related feature: having a relief similar to that originally produced by the faulting; spec. where such relief results from erosion of an obsequent scarp.

M. Davis in Bull. Amer. Geogr. Soc. 38 608 There is good reason for thinking that the high anticlinal ridges are not immediately inherited from the original uplifts, and that they really are resequent ridges and not consequent ridges. 1941 C. A. Cotton Landscape xxiii. 265 Resequent fault-line scarps..are commoner than obsequent. 1970 R. J. Small Study of Landforms iii. 105 It is invariably impossible to decide in actual cases whether or not an obsequent scarp has previously existed along a fault-line (and thus whether the scarp in question is resequent or not). 1984 R. J. Chorley et al. Geomorphol. vii. 173 Stability along the fault plane may continue but renewed erosion produces a further excavation of the fault to produce a resequent fault-line scarp.
